Mechanical anchors, often called headed bars, are secured to the end of a length of reinforcing steel bar (rebar), creating anchorage within the concrete. This approach greatly simplifies reinforcing bar placement and reduces congestion. Headed bars are often used as a replacement for hooked bars. ERICO provides a variety of headed bar solutions including the LENTON TERMINATOR. The LENTON TERMINATOR incorporates the time-tested and field-proven LENTON tapered thread to attach the head to the reinforcing bar.
